High impact information on lithium fluoride

• CyberKnife treatment plans were developed for two hypothetical lesions in an anthropomorphic phantom, one in the thorax and another in the brain, and measurements were made with LiF thermoluminescent dosimeters (TLD-100 capsules) placed within the phantom at various depths and distances from the irradiated volume [1].
• The over-response of LiF TLD-100 rods, against a calibrated ion chamber having a photon energy-independent response within 2%, was found to be not exceeding 2.5% at a depth of 10 cm in the phantom as compared to a depth at 1 cm, for a precision of the order of +/- 1% (1sigma) in the TLD measurements [2].
• In-phantom response of LiF TLD-100 for dosimetry of 192Ir HDR source [2].
• The properties of LiF:Mg,Ti (distributed as, e.g., TLD-100 or MTS-N), the most frequently used thermoluminescent detector, have been optimised for measurements of sparsely ionizing radiation (gamma rays), typically encountered in radiation protection or clinical dosimetry [3].
• Thermoluminescent dosimeter TLD-600 and TLD-700 were used to determine the thermal neutron flux within a Plexiglas phantom irradiated under the Nice Biomedical Cyclotron p(60)+Be(32) fast neutron beam [4].

Biological context of lithium fluoride

• The 200 degrees C TLD-700 response agrees well with the depth dose spectra, except for small changes due to the varying linear energy transfer (LET) distributions [5].
• LiF:Mg,Ti (TLD-100) extruded ribbons and cleaved crystals were exposed to monoenergetic photons of 275-2550 eV energy to determine their potential usefulness as radiation dosimeters for radiobiology experiments at these energies [6].
• In this study, the temperature-induced variations in the TLD-100 response and the modifications in its glow peaks are investigated in real environmental exposure conditions in Riyadh, Saudi Arabia, where ambient temperatures during summer reach >45 degrees C and with relative humidity of <10% [7].

Anatomical context of lithium fluoride

• Patient dosimetry was performed using LiF TLD-100 chips placed near the breasts and gonads for 2 h following tracer injection [8].
• PURPOSE: The radiation dose to the lens of the eye, skin, thyroid and brain of patients who underwent diagnostic and interventional radiological procedures of the lacrimal drainage system have been measured with thermoluminescent dosimeters (TLD-100 and TLD-700) by using an adult male and female Rando phantom [9].

Associations of lithium fluoride with other chemical compounds

• The radiation sensitivity of zircon was by an order of magnitude lower than that of TLD-100 [10].

Gene context of lithium fluoride

• This study compared the relative effectiveness of TLD crystals LiF:Mg,Ti (TLD-100) and LiF:Mg,Cu,P (TLD-700H) for clinical dosimetry, focusing on reproducibility, linearity, and energy response [11].

Analytical, diagnostic and therapeutic context of lithium fluoride

• TLD-100 (3 x 3 x 0.9 mm3 chips) measurements were used to measure the distribution of dose over the proctoscope surface as well as the central axis dose-rate distribution [12].
• The dose-rate distributions about the applicator were determined using a combination of thermoluminescent dosimetry (TLD-100 detectors) and radiochromic film dose measurement techniques along with Monte Carlo dosimetry calculations [12].
• Application of glow curve analysis methods to radiotherapy mailed dosimetry with LiF TLD-100 [13].
• Energy response of LiF (TLD-100) and CaSO4:Dy TL dosimeters to different diagnostic X-ray spectra has been studied [14].
• The thermal neutron sensitivity of LiF (TLD-700; Harshaw): the effect of sample size and batch origin [15].
